The lack of concentration and the crease in the neck section or its fixed section can not be airtight. There are two fixed holes on the valve plate, which can be fixed to the positioning post on the valve head, and the piston body is in the cylinder block. When actuated, the valve piece has a split-opening action to control the gas in and out with the action of the piston body, and is a piston body structure with high intake efficiency and durability. [Prior Art] A piston body that is conventionally applied to an air compressor has a main structure in which a valve passage of a piston body is provided with a vertical communication passage, and one end of a resilient metal valve piece is fixed to the valve head, and other parts are fixed. Completely closed on the channel, when the piston body reciprocates in the cylinder chamber, the valve will open and close at a high frequency, and the maximum stress at the fixed end of the valve plate is opened and closed. The stress generated in the top plane of the flapping valve head during the operation often causes the fixed end to be deformed and bent, so that the valve piece cannot form an airtight effect on the passage, and the compression function of the air compressor is lost. The inventors have felt that the valve plate is designed as an outer ring piece to connect an inner piece, so that the valve piece is divided into two-stage open state and subjected to less stress, which is less likely to be damaged than the previous structural design. 5 [Description of the Invention] - The present invention refers to a piston body structure of an air compressor, in particular, the structure of the valve plate of the type of the seed body is improved, and a valve piece is formed on the valve body, and the valve piece is provided. There is a ring inner space, the valve piece is divided into two parts of the inner and inner discs, so that the vibration stress of the valve piece when striking the valve head can be less than the loss of stress concentration and the neck section Or the solid is only abundance, and the finger marks can not be airtight. On the cymbal piece, there are two fixed holes, which can be fixed to the positioning post on the valve head, and the piston body is driven into the valve body to move into the valve piece. The piston body is actuated to open the closing action to control the gas out to be a piston body structure with high intake efficiency and durability. [Embodiment] First, referring to the eighth figure, which is a schematic diagram of an air compressor, after a motor (7) is disposed on the base (5), the pinion (71) of the motor (7) is meshed with a large one. On the gear (72), the large gear (72) is stacked with a weight (74) and pivoted to the base (5) with a shaft (73). The weight (74) is provided with a eccentric tip. (75) and spliced to the shaft hole (22) of the piston body (2). When the motor (7) rotates, the pinion (71) in front of the motor (7) rotates the large gear (72) and the weight (74), and the eccentric (75) on the weight (74) rotates the piston body. (2) The shaft hole (22) causes the valve head (23) of the piston body (2) to repeatedly move in the cylinder block (6), thereby feeding air into the gas collecting seat (61) and diverting it to the manifold (62) (63) (64) (65) and hose (641) (651) are installed in devices such as a barometer (8), a gas nozzle (9), a venting valve body (81), and the like. The most important feature of the present invention is that the piston body structure 'please refer to the first to third figures, the piston body (2) basically has a valve head (23)' valve head (23) top surface 1330687 (24) A positioning post (25) (26) is provided with a top surface (24) and a passage (28) extending through the valve head for allowing gas to flow from below the valve head (23) through the passage (28) to the valve head (23) Above and into the cylinder chamber (69); an annular groove (27) is provided around the passage (28), in which an annular gasket (3) can be placed, the height of the gasket (3) is slightly extended The horizontal plane of the groove (27) can have a better airtight effect when the valve piece (1) covers the gasket (3) of the valve head (23), or the valve piece (1) is opened and closed. When the valve head (23) is tapped, the noise of the slap can be reduced. A piston rod (21) is arranged at a lower end of the valve head (23), a shaft hole (22) is arranged at a lower end of the piston rod pi), and an oil seal ring (4) is arranged around the valve head (23) to make the valve head (23) ) It is airtightly combined with the peripheral wall of the cylinder chamber (69) to prevent gas leakage. a valve piece (1), the valve piece (1) is provided with an annular inner space (14), and the circular valve piece (1) is divided into an outer ring piece (Π) and an inner ring piece (13). In part, the outer ring piece (11) and the inner piece (13) are joined to form a neck section (12), and a second positioning hole is formed on the ring piece (11) opposite to the neck section (12). (15) The fixed section of (16) (17). The valve piece (1) is fixed to the positioning post (25) (26) of the top surface (24) of the valve head by two positioning holes (15) (16), and the inner piece of the valve piece (13) • The passage (28) of the valve head (23) can be closed, and the whole assembly is completed as shown in the second figure. Referring to Figures 6 to 8, a gas collecting seat (61) is provided on the cylinder block (6), and a gas collecting chamber (60) is provided in the gas collecting seat (61), and a top cover of the gas collecting seat (61) is provided ( 66) There is a spring (67) and a valve seat (68) underneath. The valve seat (68) can block the passage of the plenum (6〇) and the cylinder chamber (69) by the spring force of the spring (67) (69〇 ); a plurality of manifolds (62) (63) (64) (65) are arranged around the gas gathering seat (61), and the manifold (6 sentences can be connected to the hose (641) and the gas nozzle at the end (9) The manifold (65) can be connected to the hose (651) and the gas material (8) at the end thereof, and the manifold (6· can be installed such as money m (8i). When the 7 1330687 piston body (2) is pushed up, the air The valve seat (68) can be pushed open to the plenum (60), and then output to the gas nozzle (9), the barometer (8), and the deflation valve body (81) by the manifolds. Figure, when the piston body (2) moves down in the cylinder block (6), as shown in the sixth figure, the air enters the valve head from below the valve head (23) via the passage (28). Above the cylinder chamber (69), at this time the inner piece (13) and the outer ring piece (11) of the valve piece (1) will be lifted up (see the fourth and fifth figures), and vice versa. When the piston body (2) moves upward in the cylinder block (6), as shown in the seventh figure, the valve piece (1) closes the passage (28) of the valve head (23), and The air that compresses the cylinder chamber (69) enters the plenum (60) of the plenum (61). The piston body (2) of the air compressor reciprocates up and down in the cylinder block (6) at a high frequency. That is, the metal valve piece (1) will simultaneously perform the opening and closing slap action at the same high frequency. In the present invention, since the valve piece (1) is provided with an inner space (14), the entire valve piece (1) is subjected to compressed air. The stress is evenly dispersed, so that the neck section (12) and the fixing section (17) of the valve piece (1) are subjected to strong stress or stress concentration, which is sufficient to protect the entire valve piece (1) from being protected. The deformation and bending or damage can exert better airtight effect and fruit. The structure of the present invention has its novelty, and the invention can overcome the lack of deformation and bending of the conventional metal valve piece, and has For its practicality, a patent application is filed for this purpose. 8 1330687 [Simple description of the diagram] First picture: Department Fig. 2 is a perspective view showing a piston body of the present invention.
